Starting from the cyclic ketones 1a-d, the dienes 3a-e were prepared. The ring closing metathesis reaction of these dienes using the Grubbs catalyst 5 provided the corresponding spiro ethers 4a-e in good yield. Force field calculations indicate that the conformer with the oxygen in axial position is favored.
New [Ru3(CO)12]-Based Catalysts with Imidazolinium Salt, Diimine, or Bis(oxazoline) Ligands and Ruthenium Bis(oxazoline) Complex for Tandem Isomerisation/Claisen Rearrangement of Dienyl Ethers - X-ray Structure of [RuCl{(R,R)-bis(iso

The reaction of various 1,7-dienes in the presence of the three-component catalyst A: [Ru3(CO)12]/imidazolinium salt/Cs 2CO3 (1:1:2) leads to the tandem alkene isomerisation/ Claisen rearrangement affording γ,δ-
